I already own Bryston BHA 1 and Musical Fidelity M1 HPA but I am not completely satisfied with the sound out of these two headphones with both amplifiers (Bryston a bit too cold with hd 800 and bass tight with LCD 2 even in balanced mode and Muscal Fidelity seems to lack punch with both headphones).
I also have a pair of Grado SR 325 iS and I am really happy of their sound signature and punch when paired with the Musical Fodelity.
I am seriously thinking of selling the Bryston to buy a tube amp.......
Willing to spend not more than 2.00/2.500 €.
Please help me in finding a good tube amp I can use with both headphones.
